Het CentOS probleem
On 8 December 2020, the CentOS Project announced that the distribution would be discontinued at the end of 2021 in order to focus on CentOS Stream. The community's response to this announcement was overwhelmingly negative. Soon thereafter, CentOS founder, Gregory Kurtzer announced a new project to continue the original CentOS focus, which became known as Rocky Linux -- https://rockylinux.org/ . CloudLinux created AlmaLinux -- https://almalinux.org/ to provide a community-supported successor to CentOS Linux, aiming for binary-compatibility with the current version of RHEL. A beta version of AlmaLinux was first released on February 1, 2021, and the first stable release of AlmaLinux was published on March 30, 2021.
Rocky Linux appears on belnet -- https://ftp.belnet.be/mirrors/rockylinux/ and looks like a first choice right now. CentOS-(up)streams is a Fedora, a distro impossible to teach with.

If you use CentOS 8, you might have noticed that starting from January 31, 2022, installing packges with yum no longer works with an error No URLs in mirrorlist, similar to the following:
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
If you still need to run your old CentOS 8, you can update the repos in /etc/yum.repos.d to use vault.centos.org instead of mirror.centos.org . Here are two simple commands to do this, both need to be run with sudo:
$ sudo sed -i -e "s|mirrorlist=|#mirrorlist=|g" /etc/yum.repos.d/CentOS-*
$ sudo sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" /etc/yum.repos.d/CentOS-*
